of highly automated large volume production. The advantages of this new technology are clear. With respect to occupational safety, MQL offers reduction in permissible exposure to mist in work area, [2] and numerous advantages over water-mixed metalworking fluids. Minimum quantity lubrication is a total-loss lubrication method rather than the circulated lubrication method used with emulsions. This means using new, clean lubricants that are fatty-alcohol or ester based. Minimum quantity lubrication is a new concept in lubrication methods where in a metered quantity of lubricant is delivered by the MQL system to the machine / process under consideration. These systems normally employ piston pumps for application due to accuracy of the piston pump in delivering exact quantity of fluid. Pump noise can be categorized into two basic classes namely the audible noise that can be heard and needs to be controlled to maintain comfort level in the industry / workshop where this device is used and secondly the pump noise in form of pulsations of flow which is more significant because it one of the major cause of inaccuracies in the metered quantity of fluid. The variable forces inside the pump mainly depend on variations of pressure within the pump. They change periodically with the change of the load at the displacement elements. [3]
Abstract - Minimum quantity lubrication is a new concept
in lubrication methods where in a metered quantity of lubricant is delivered by the MQL system to the machine / process under consideration. These systems normally employ piston pumps for application due to accuracy of the piston pump in delivering exact quantity of fluid. But noise generated from this pump is the main problem in industries. Pump noise can be categorized into two basic classes namely the audible noise that can be heard and needs to be controlled to maintain comfort level in the industry / workshop where this device is used and secondly the pump noise in form of pulsations of flow which is more significant because it one of the major cause of inaccuracies in the metered quantity of fluid. The proposed design is developed for R-11 pumping element to be used in one such MQL pumping unit. The purpose of paper is to discuss the design and analysis of two critical components namely the neo-polymer membrane (Eartlon-66) and the diverter that play a significant role in noise reduction. The paper also discusses the effect of change in discharge from pump on the audible noise from the system. Key Words: Diverter, Minimum quantity lubrication, neo-polymer membrane, Piston pump.
1. INTRODUCTION
2. LITERATURE REVIEW
Minimum quantity lubrication (MQL) has increasingly found its way into the area of metal cutting machining and, in many areas, has already been established as an alternative to conventional wet processing. In contrast to flood lubrication, minimum quantity lubrication uses only a few drops of lubrication (approx. 50 ml to 500 ml per hour) in machining. [1] Today, the enormous cost-saving potential resulting from doing almost entirely without metalworking fluids in machining production is recognized and implemented by many companies, primarily in the automotive industry. While in the early 1990s small applications (sawing, drilling) were done “dry”, today we are able to produce cylinder heads, crankcases, camshafts and numerous other components made of common materials – such as steel, cast iron and aluminum – using MQL in the framework

Anurag goyal, Jasvir S. Tiwana, Amrit Pal [1] has studied the Minimum Quantity Lubrication in machining. minimum quantity of lubrication (MQL) is newly developed economic and environmental friendly alternative to completely dry or flood lubrication. MQL refers to the use of a small amount of cutting fluid, typically in order of 500 ml/hr or less, which are about three to four orders of magnitudes lower than that used in flooded lubricating conditions, MQL technique consists in atomizing a very small quantity of lubricant in an airflow directed towards the cutting zone [1]. D.V. Lohar and C.R. Nanavaty [2] have explained in his paper about advantages of Minimum Quantity lubrication (MQL) in maintaining the regulations of occupational Health
